Hi i have a contour plot showing a depth profile of nutrients in the ocean over time however when using meshgrid to interpolate it doesn't seem to be calculating any values for the upper most layer?
[xq,yq] = meshgrid(min(date):1/12:max(date),-4000:100:0);
varq = griddata(date,-depth,var,xq,yq);
using the above code it plots a contour map from -4000m up to -100m but only white space from -100m to 0m? The only way i have been able to change this is by changing the steps in the meshgrid from -4000:100:0 to -4000:0 however this creates a very grainy contourplot and ideally i would like to keep the averaged smoother plot? how can i do this without loosing the surface data?
